An instant messaging program, iChat enables Mac users to chat with not only other Mac users but also with other IM users on different services, such as AIM and Google Talk. For a business owner or employee, saving your conversations with other employees or clients in a transcript makes it possible to review the information at a later date, helpful if you are looking for a specific piece of information. Once you have set your iChat settings to automatically save your conversations, you can view them at any time in your Documents folder on your Mac.
